I'm only just picking up Python again after learning a couple of years ago (after not touching programming since the old c64 days), so forgive me if this answer is obvious;

Is it (relatively, depending on experience) trivial enough to build a python based scraper that could read the contents of a note and make use of that data?

Just thinking along the lines of GitHub type use cases where code can be called from a simple note and used by a page or an app?
